' AcooUN'rmG SYSTEM.

'To'all il-lzom it may concern:

Be it known that I, VILLIAM J. CnUMP- TON, a' citizen of the United States, residing and cost-accounting,-where theentries made.

at'Evanston, in thecounty of Cook and State of Illinois, have invented a certain new-and useful Improvement in Accounting Systems, of which the following is. a full,'clea-r, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates .to electrically con-' trolled and automatically governed accounting systems. 3 It is designed to provide. for' extensive and complicated accounting transactions of various kinds and is particularly a-pplicable tosystems 'of-time, wage-, ob-,

' 7 are both functions of time-and other factors.

Broadly considered, my present-invention isbased upon and is an elaboration of the underlying idea"shown in my application,

' whereiiLI have set forth what maybe termedja simple system operating on an intercurrent other words, the registers are the actuations of the-individual..registers,'a

plan; Thatis-to' say, the individual registers are so connected with a sourceof 'electrical impulses that theactuating current 1S sent through the registers n succession,' n

one after the other. In order o summate totalizer 'is connected in a common wire forming partof all of the circuits which are 1 successively closed through the electromagnetic actuating mechanisms of the registers.-

Now, ii the invention which forms the subject matter of this application there are several simple systems which concurrently discharge into a substation. Each :substation comprises one or more receiving and transferring mechanisms of which I shall system, according to whether't-he composite systems discharge separately into the generic station or are; coupledtogether and discharge as one whole into the generic slation. Finally, if the conditions demanded it, several of such compound or multiple composite systems could be connected up and led into the central receiving station, where all the grand totals-appear. v

I mightperhaps beable to render the.

above general statements a little clearer if 'I give a: concrete example of how -my inyent-io-n might beput to actual practice. Let it be supposed that in a certain establish- 'ment, a car is to'be 'buil-t." This'car will, let us say, constitute job No. 6. There would be-pr,o 'ided a grand .total register for indicat n the total cost of the job. This grand totalregister might .be 'called the central station register for that particular job. Into thiseentral station there would discharge three; substations representative of the metal work, woodwork and paint work done in connection with the building of the car.

There. would also be a separ ate substationfor the entry of the cost-'of'ma-terials. This .s'ubstation differs from the other substations only-kin the fact/that it is manually controlled while the other substations are timecontrolled. Into the metal work substa tion' would dischar e several simple syst-ems"let us say tl1ree-representing the three departments of casting. machine work and forging, in each of which departments would be employed a number of workmen. The wood work substation would receive the total cost of the work done in the difl'erent wood working departments. say, the department-cf mill work and that of. hand Iwork. The paintwork substation will receive the total cost of the work done -'in the various paintingdepartments, as. for

instance, the department where the outside.

finish on paint work is done and the department where the inside finish is taken care of. It will be seen, therefore. that in the above illustration we may have .a plurality of simple systems. The three simple svsleius which have ,to do with the metal work dis charge intoa substation identified as the metal work substation. The two simple systems which represent the wood work (ligcharge into the wood work substation. The two simple systems which have to (in with the paint work discharge iiuo the paint work substation. These three substations in turn discharge into the central contain the following among the main charreceiving station, where the cost total of the job is indicated. Another way of applying my invention would be inacase where a very large number of men is to be handled. In that instance a simple system might be considered as having a limited capacity, say, one thousand men. Then three simple systems would be used to take care of three thousand men. These simple systems would, before, discharge into a substation. By simply increasing the number of the simple systems there is hardly alimit to-the number of men which might thus be handled. This will give some idea of the great flexibility and adaptability of my invention, especially when it is considered that the system operates with equal facility in the accumulating as well as in the decumulating direction-as will be fully explained in due course.

I'have already mentioned that a su bsta tion comprises a plurality of receiving and transferring mechanisms,- which I call a composite'motor unit. These units are or; peculiar and novel construction in, that they receive the accumulation of individual re isters and may discharge such accumulations as fast as they take-place or atfany time thereafter. In other words, the discharging of these motor units may be either concurrently or intercurrently with the accumulations therein. The decu'mulations are auto-. matically transferred into a more'generic receiving-mechanism. As herein shown, several simple systems are arranged to be con-. nected, in multiple under the; control of one set of electrical controlling mechanisms and to accumulate their entries concurrently into the composite motor units at the associated substation.- -The substation may be .connected to discharge into a more genericistation as rapidly as the accumulations appear in the substation, :or the aceumul'ationsmay be held and transferred later'into' the central station. In other words, a substation is really a sort of reservoir into which entries will, as; it were, flow either to be stored therein for future withdrawal or to be' with-- drawn as they flow in. I. have, therefore, called these substations reservoir substa-- tions. Like any reservoir, the inflow into these substations is independent of the. outflow therefrom, and vice-verse.

The specific circuits herein illustrated, while they provide for the simultaneous discharge of any or all composite motor units of any substation, require that ,the's everal' or corresponding motor units of the sey eral substations be discharged successively. However, it is obvious'that the corresponding units could be connected together bymeans of differential mechanisms to 'efifect-i their simultaneous discharge.

Considering my invention from a more specific point of view, it will be found to,

.a'cteristics-besides those already referred to: laach register or counter is controlled and driven independently of anv other counter by means of a three-phase motor, so that the amount of its actuation is entirely dependent upon the numberof cyclesim pressed upon the motor. 'lhese threephase motors are adapted to actuate. the counters in either direction, according tii the. order in which the electrical impulses are impressed upon the different phases at the motor. i To secure actuation proportional to the rate oi: wages, the wage-register and its connected job-register receive for each different ate a difl'erentnumber of electrical cycles within a given period of time. This is brought-about at a centralized point by 4 'means of a time-controlled distributor and a source'of current. The rate-controlling meeh'anismis operated from a cross-connecting switchboard, and all that is necessary to change a workmans rate of wages'is to change the proper plug-connection in the switchboard,=whereby-the number of electrical cycles is varied to produce the desired change of rate.

A workmans wage register is operatively connected when the same is started by the workman throwing his switch to the in position. For this purpose I have provided means whichareso connected into the system that when a'workmans plug is out of the jack of the job switchboard, the work' mans wage-register is automatically connected with a waste wage register. When, however, the plug is in ,the -jack, the worlo, mans wage-register is disconnected from the waste-wage register-and. eonnected'to the job-register. In this way the workmans wages are charged against the proper effective account by theforeman plugging in the proper job-jack after the workman has registered in. I

To provide for the making of entries not functions of time (as, for instance, the costof material), I have devised a noyel form of register which may be quickly-adjusted manually to any indication and then con nected up in circuit to discharge the initial amount set up into a more generic receiving mechanism. These registers are intact manually controlled substation units and are used for entering the values of materials, etc.,

Many other novel features and arrangements characterizing my invention will present themselves in the course of the-detailed descriptibn of the embodiment shown in the accompanying drawings, in which-e Figure 1 shows very diagrammaticallya compound system comprising simple systerns, reservoir substations, and a central station; Fig. 2 shows a simple systemeon 13o nected'- up .-to-'.' discharge vinto-a substation.

In a similar manner the groups of simple" systems A2, B2, C2" and A3, .B3, C3 discharge into the reservoir. substations S2 and S3,-respect ively;" T he three reservoir substeitionsdischarge into thecentral station'CS, where the grand total registers are located. If we iinagine this compound systemas established in a factory, one might consider each group of primary systems and v the associated reservo r substationas repref .senting a room or floor in the factory, with each simple system representing 'oneof the departments inthat room'. Whatever work there is done on any job in process, the costof that job is indicated by the amountof wages earned .by' the workmen employed on that-job in the different rooms and tie-- partments will be'finally indicated in the proper register in the central station. Each.

department'has, ofxacourse, its job-registers for indicating the cost of thejob so. far as that department alone is concerned The while the cost of the workdone on the job'by the depart-merits on. the. same floor. (in the example-assumed) 'will be totalized and, if desi-redh indicated in the reservoir station associated with those departments. The totalizations or'. -i'ndications .of .the reservoir sub.-

stat-ionslare transferred into and totalized by-the proper job total register at the central station. The partindicated in Fig. 1

by represents the'material substation, where the "cost of materials, etc, is added to'any particular j,ob.' The indications at.

this material substationf ,are. added to the indications coming from the: reservoir substations. 1;;111 this way thejob'total registers at the central station will each indicate the total'cost of any particular job.

It will perhaps facilitate an understanding of the'system' shown in Fig. 1 if I first takeup the description of the three-phase motor, which is used for operating each of the registers shown in the system. This motor'isi'illustrated in Figs. 6 and 7. W'ithin the casing-'1 jarehoused electromagnets, 2, 3,

and 4,. each comprising a. magnetic core '5 and axwinding 6. One end of the core of '-each magnet is held infirm contact with an :ironyoke'l, which is of rectangular shape,

and on the inner 'sideof the front portion of this yoke is provided a pole piece 8. The

cor'e fiat its front end is provided with a similar pole piece 9. The space .betwe'en these-projections constitutes the air gap'of the magnetic circuit for each magnet; On ashaft .10. are mounted three armatures 11,

indicated in outline and shown as radially displaced with respect to the poles of the armature belonging to -mag'net 4. The purpose-of thisangular displacement of the armature poles is to cause upon successive energizations of the electromagnets, a substantially continuous rotation of the armature shaft 10. For instance, when electro- .magnet 2 is energized and attracts its armature into a position where it spans the air.

gap, the armature of the electromagnet next to be energizedviz., magnet f3,-will be -moved into a posit-ion to be given a one-step movement when electromagnet 3 is energ1zed.,v Similarly, the energization of electromagnet 3 moves the armature belonging to electromagnet t into a position to receive a one-step advancement in the same direcbe apparent from this that the rate of 21C.

. 1o tuation of shaft depends upon the fre- .tion as the other armatures did when the .electromagnet 4; is energized. In'like mannerdoes the energization of electromagnet 4: place the armature of .electromagnet 2,-

again in position to receive a one-step advancement. This cycle of operation is repeated over and over againasthe electromagnets are successively energized. It will quency of the current ii'npulses sent through the windings of the clectromagnets. So that.

by regulating or predetermining the frequency of these impulses, the rate of actuation of shaft 10- may be controlled as desired. It will also be apparent that the di rection of rotation of this shaft depends upon the order-in which the clectromagnets are energized. If the magnets are energize in the order above named, the armatures ,will actuate shaft 10 in, say, a clockwise direction. If the electromagnets be energized in the reverse. order, the armatures will actuate the shaft in the reverse direc-' tion. his is due to the. factthat the electromagnets will close the iron path for the flux always by the least movement of the armature. For instance, in Fig. 6 the'armature of the electromagnet I will beac tuated in a clockwise direction when the electromagnet. is energized. The number of poles in each armature and the angular displacement of the arm'atures upon the shaft is such that the direction of rotation of the shaft is controlled by the order in which th impulses are impressed upon the electromagnets, as above stated. I have conveniently termed this device a three- 'phase motor, because the current impulses are sent through the motor in cycles of three impulses each. In other words, it might be truly said that my new form of motor is operated bythree-phase current-impulses,

because the impulses do follow each other in a manner similar .to the waves of a threephase alternating current. I am aware that in ordinarily speaking of a three-phase motor we mean a motor in which rotation is caused by rotating the magnetic field produced by a three-phase alternating current. Although this is not the case with the motor which I have just described, still, because of-thc analogy between a three-phase alternating current and athree-phase current impulse, I have designated my motor as a three-phase motor. In order, however,

" to avoid confusion I use the'term threephase within quotations when applied in connection with the motor which I have above described.

In work ng out the system shown in Figs. v 1 and 2 I have found it very convenient to employ registers having each associated therewith a motor in which three-phase impulses were used, as above described.

However, I would have it understood that so far as themotor itself is concerned I do not intend to be limited to a structure employingany specific number ofelectromagnets, such as three. It should be apparent that this motor is complete in itself and may be used for actuating various'other devices besides registers, and in adapting this motor to various other uses it may be found desirable to use a different number of clectromagnets. In any event, the number of impulses, sent through the motor during every cycle of operation is equal to the numberof electromagnets employed. For this reason I should perhaps have used the term multiphase in describing my motor, but, as above stated, I have referred to'it as athree-phase' motor because that is the kind of motor which I found convenient to use in connection with the system herein set forth. vHowever, as set forth in certain of the appended claims, I do not intend that my designation of my motor as, a threephase motor shall place a limitation upon this feature of my invention.

In Figs. 6 and 7 I have shown a register 13 associated with the motor. The actuations of the armature shaft 10 are transmitted to the register from the gear 14; fixed uponthe shaft 10 to the idler 15 mounted in the partition 16 of the motor casing, and thence to the gear 17 of the register. The gear ratio between the actuating shaft 10 and the regis- 'ter is such thatthe lowest order numeral wheel receives a. one space actuation for every electrical cycle sent through the associated motor. I might say right here that when I use the term cycle in connection with the operation of the specific embodiment of my system, I mean a set of impulses consisting of an impulse in each phase. It is ob vious that'register-actuating motors may be used that will actuate the registers by singlephase impulses.

' Being now in a position to understand how the three-phase motor actuates ltS associated register, we will turn our attention to the'circuit arrangemeins 'ud various actuating devices shown in Fig. 9. The registers in this figure are each diagrammatically indicated by three circles arranged in a horizontal row. Each row of circles is supposed to represent the three electromag- .n'cts of the register actuating motor, no attempt' having been made in this diagrammatic showing to indicate the register itself. It will hardly be necessary to explain here that in an establishment where a system is used for automatically taking account oi a workmans time and wages, each workman is provided with an individual wage-register and an individual time-register. Besides these there are a number or jol'i-registers, each representing a particular job. When a orkrnan begins work in the morning he throws-a switch which automatically sets h s iwage-register and time-register golng,

the time-register'indicating.- the, 'time for which he is to be credited and thewvage register indicating the amount of wages which the workman receives during. that time in accordance withlhis particular rate. v

The. cost of anyparticular job is taken care of by .totalizingun"the'job-register the'indications of thefwage-registers' belonging tothe workmen assigned toJthat -job. "Fig.-v

7 Before attempting to trace, the various energizing circuits, it will perhaps-be-betterfi to take up first thedescription of -theym'echw anism'thati controls the circuits. The actuah ing shaft AS is adapted to be connectedwith a suitable source of power for -uniform rotation. It is desirable that ,the rotations of.

the shaft be time-controlled. Mounted u on this shaft-is a serles of ratewheels R1," 2,. R3, and R4, provided with teethinthe ratios of one, two, three and four, respectively.

' These. rate-wheels have associated therewith thegears ilO, 21, 22 and 23, respectively.- These gears are loosely mounted upon the rate-shaft RS and tiach-is-associated with a clutch. The movableor- 'shiftable' parts of: the clutches consist of the sleeves 20, 21, 22', and 23" respectively, keyed upon the shaft RS so as to rotate'therewit-h. It will be observed that the-hubiof each clutchge'a'r is provided with teetli'which are adapted to receive between the spaces thereof the-teeth on the adjacent end of the associated clutch sleeve. So-that, when the sleeve is actuated toward the gear, the two parts-will become locked andthe motion of the gear member nf the clutch imparted to it by its associated rate wheel will be' transmitted-through the i clutch sleeve to the shaft RS. The position of the clutch sleeves is controlled by the electromagnets'rl, r2, f'1:3 and-1'4. Whenever one of these electromagnets s energized itdraws up its armature 24, whichTfor ns one arm-of a bell crank, the other arm 25 of which engages ln agroove in the assoclated clutch sleeve. so that the latter may be 'free to rotate. The'bell crank-being pivoted at- 26, it-- gization of the electromagnet, the clutch isleeve s drawn outof-engagementwvitlr-its gear bythe spring 27. As will appeal" later, no two-0f theelectromagnets are energized atthe sametime, so that it is impossible for more than one-clutch'to be in operative po- F rorn; what has' been said before respectactuating shaft AS a certain amountot receiye an amount jof actuation equal totwo,

because' theratewheel R2 has a ratio twov times that of the. rate 'wheel' R1, and will therefore actuate the gear wheel 211twice ated.- .\Vith-'lectrolnagnet r3 energized, therate wheel R3 will impart to the rate shaft an amounfof rotationequalto three, through 'i the'amo unt that the gear wheel2Q was actutheclutchcontrolled by that electromagnet.

The. mechanism' for controlling the cir cuits of the electromagnets is a very-simple one, comprising the rate controller commutator-RC. The ratebrush 'r'b fixed u on the selectorshaft SS is arranged to ma ecsuc-ycessivecontact with the segments as this shaft is rotated. i-In the'present instance theratecontroller has'six segments, the same number that the time-register selector TS and the wage-register selector WS have, because the system has, for the sake of illusselectors was cq mgtqt e uinbe r of 1.3o,

tration, been designed to take 'care 'of six I workmen. The number of. segments in these The segments of the rate controller RL rate plugs rpl, 1722, 7723, i714} 1725, "I796. segmcnt No. 1 being connected with plug rpl, segment No. :2 with plug 1722; etc. The rate brush 1'? is connected with the power main m, the other main m being connected through conductor 37 with one end of the rate electromagnets. The other ends of these clcctromagnets are connectedeach with-a jack strip -of the rate'controlling switch board RCS. Thus, magnet a1 is connectedwith jack strip 51, magnet 1'2 with jack strip, etc. Let us supposethatit is desired 'to operate a workmans wage-register at the rite represented by the rate wheel R1, which is the lowestra'te in the system shown. In that case rate plug a'p'l, belonging to workman No; 1, isinserted in any one of the jacks of the strip 81. lVith the rate brush in engagement withsegment No.1 ofthe rate controller RC, a circuit may betraced from the positive main/m, through the conductor 'irfto the electromagnet 6'1, thence through the," $1, to' the rate plug 1791; to segm ent"Noi 1,';toratebrush ab, and through the conductor 38 back tothe negative mainm. It is ofcourse to be understood thatthemainsm and m, are connected with a suitable sou ce of-clec'tric current.

' The'electromagnet r being thus energized, will draw'the clutch sleeve 20' into engagement with the gear wheel 20, whereby the actuation of the latter by the rate wheel R1 will be transmitted to the rate shaft RS,

causing the wage disks 'wdl, wclQ, wd3 to close the circuit through the connected registers a certain number of tunes during one revolution of the actuating shaft AS.

The amount of movement which -the disk 30 imparts to the selector shaft SS through the Geneva wheel 32 during every revolution of the shaft AS, is just sufficient to cause the selector brushes carried by the selector shaft SS to move from one segment to the next succeeding one. So that the rate brush '1'?) will remain on segment No. 1 during one complete revolution of the shaft AS. If workman No. 3, let us say,-is to be connected with a higher rate than that controlledjiy rate wheel R3, then his rate plug 1773- is inserted in any one of the jacks in strip-'83.

With this connection made, the circuit through the electromagnet 1'3 will be closed when the rate brush rb engages segment No. 3. During this engagement the rate shaft RS willhe actuated by the rate wheel R3 through the associated clutch gear an amount equal to three times that which it received from the rate wheel R1. Tis means that the wage disks wdl, 11x12 and wd3 will cause three'times as many current ..pulses to flow through the connected regigi ers as was the case when the rate shaft .is actuated by rate wheel R1. To put it t icretely: If we l'assume that the lowest rate wheel R1 represents a rate of five centsan hour, the rate wheel ,R-3 will represent a rate of fifteen 1 cents anhour. The gear ratios are such that ;.the number of 'impulses sent through the connCtcdregisters by the wage disks will actuate the register-sin accordance with the workman's particular rate. It'will be noticed that the rate-controlling circuits are entirely independent of the register-actuating circuits. Upon the shaft AS is also 31 adapted to enter one of the recesses in the Geneva wheel 32 for actuating the same one step during every revolution of the shaft AS. hen the tooth 31 is out of engagement with the wheel 32,-the latter is locked a gainstmovement. The Geneva wheel 32 is secured upon the selector shaft SS. It will be obseryed that the'wheel 32 has six teeth. so that the selector-shaft SS will make one complete revolution for every six revolutions made by the actuating shaftzAS. ,The selector shaft controls the operation of the mechanisnr which selects the registers for connection-with the source of actuating impulses. i p

As illustrated herein, the time-register selector TS comprises a commutator having six segments, each of which has connected therewith a conductor for carrying the impulses to a particular register, as will presently be explained. A selector brush fl; is securely mounted on the shaft SS and serves to make contact with the segments successively as'the shaft is rotated. The wage-register selector \VS is similar in constructicn to the time selector and has for its function the selecting of the proper wageregister.

The time disk TD. rigidly mounted on the actuating shaft AS imparts one revolution to the associated Geneva wheel 32%. mounted upon the time shaft is during each revolution of the shaft AS. During part of the interval in which the actuating shaft AS runs uniformly to make one complete revolut'on, the shaft will make one revolution; and during the rest of the interval the shaft its. will remain stationary, until the teeth-on the disk-TD again engage the wheel 33 at the beginning of the next. succeeding interval or period.

That is to'say,'.the first strip of jacks is connected with' job-register J1; strip No. 2 is plugs may be inserted in any one of the ing the plug of workman No. 1 is shown as which is representedby job-register J1. If, for instance, workman No. .6 were to be connected with job No. 4, then plug jp6 would be-inserted in any one of the openthe acks shouldbe such as to permit connection of all of the workmen in a department with the same job. \Vith this description of the various details of the circuit controlling mechanism, we are now prepared to follow some of the circuits in the operation of the system. Let it be'supposed that workman No. 1 moves his switchjPl to the in position and that the foreman hasinserted the workmans first strip of the job switchboard J S. We will also suppose that the workmans rate plug 7721 is inserted in one of thejacks in the strip 81 in the rate controlling switchwith the rate clutchoperated by the rate wheel R1. If, as above assumed, the rate hour, the workmans wage register will be actuated that amount during every hour. I might explain now that the rate of rotation of the-actuatin shaft AS depends upon'the Every hour, therefore each workmans register will be connected ith the'source of impulses to recelve an ,amo'untof actualVhile the shaft AS makes one revolution per man, the selector shaft SS is actuated one-sixth of a revolution, whereby the selector brushes on the shaft are moved from one segment to the next succeeding segment. A brush remains upon a segment during one revolution of the actuating shaft AS, thus keeping the circuit through the connected registers closed a sufficient length of time to permit the register to receive the highest amount of-actuation during a periodof one the men are picked up'might be other than an hour, but'by making the period just one hour, theexplanation-is simplified;

In the position shown in Fig. 2, the shaft is at the end of a revolution and the disk 30 is about to actuateithe selector shaft to selector and rate controller. Let 'us assume, however, that the selector brushes have been moved into contact with the segments No. 1, so that the wage register of workman No. 1 was connected in circuit during the last revolution of the actuating shaft AS. The ci r cuits through the workmans individual reg isters T1 and 1V1 will be as "follows: Startthe current passes through-conductor 40 to the insulated portion of. the shaft RS on and 'wdS. with the rate clutch controlled by electromagnet T1, the rate shaft RS will make one revolution during the period in which the worknians register is connected in; In the period: during whichthe rate shaft RS will receive one revolution from the rate wheel di'sks will each come once into contact with the segment on each of the wage disks, thus causing successive impulses to flow through the conductors 41, 12 and 43; or, as above explained, a three-phase impulsewill he sent through the conductors 4:1, 42 and 43 -duringevery revolution of the rate shaft RS. Bearing in mind that we call a threephase? set of impulses simply a cycle, we can say that for every revolution of the rate shaft RS the wage disks wdl, 1M2, wdi-B will allow a cycle to pass from the main source of current to the connected registers. This 13, .will'pass into the register lVT, which the wage total register, so called because. all of the impulses that flow through the individual wage registers also flow through this time of the-register lVT representthe sum of the aotuations of the individual registers hour.

In thiswa-y, the actuai l i to 2 8, From the wage total register duct'ars into any register which happens to be connected, it being understood that the registers are selected for actuation successively, one at a time, by the selector devices TS and l l jS. From the wage register 1,

' the current passes through the conductor 7 the point Y.

and from there to segment 1 of the wage so lcetor VJS. The wage brush wb being in contact with that segt'nent, will conduct the current through conductor 4-5 to the time brush it). The switch included in the conductor is, of course, in the position in which it s shown. From time lorush 151), the current passes through segment 1 of the time selector TS to the conductor to, and thence through the workmans closed switch P1 to it this point the current devidcs into two paths; one of these paths is through the workmans time register T1, as follows: From the point Y to the conductor 47, through the time register T1 to the conductors 48, 4-9, 50, and from there through the time disks M1, M2, M3 to the conductor 5]., hack to the negative main m. As already stated, the gear ratio between the time disk TDmountcd on the actuating shaft AS, and the gear wheel 33 mounted on the time shaft is, is such that the time shaftwill make one revolution during the interval that the actuating shaft AS makes one revolution. Now, with the rate shaft connected with the actuating shaft through the lowest rate clutch, it follows that the wage disks will run in synchronism with the time disks. As amatt-cr of fact, so far as this synchronisn'i hot-ween the wage disks and the time disks is concerned, it makes no diiterence how man revolutions the rate shaft RS makes during one revolution of the actuating shaft. AS: the first revolution of the rate shaft HS during the interval in which the actuating shatt- AS makes one revolution will always he synchronous with the revolution of the time shaft If, during an interval (and by an interval I mean the time during which. the shalit AS makes one revolution), the rate shaft its is geared up to make more than one revolution, the time shaft is will remain .tationary during the additionat revolutions of the rate shaft. in other words, no matter at what rate a workman's register is actuated, the rate of actuation of the time registers will. always remain the same.

liicturning, now, to the tracing of the circuits ahove commenced. we find that the sec ond path branching from the point Y is through the workmans job register J1 as and time selector TS.

follows: from the point Y through the conductor 51 to the plug jpl, thence to the conductor through the individual job register J1. From there. the currt-intpasscs through the conductors 53, 54; and 53 to the job total register JT. From there the current passes through conductors; 5G, 57 and 58, the job disks jdl, M2. M3, through the switch a" and conductor 59, back to the negative main m. A register operating at a five-cent rate will, therefore, have impressed upon it during an interval one electrical cycle. If a register is connected with a tencent rate, it will have impressed upon it two cycles during the interval in which it 1s selected for actuation. To allow two current cvclcsto pass through the circuit, the

rate shaft RS will receive two revolutionsduring an interval by the rate wheel R2.-

For a fifteen-cent rate, the actuating shalt AS will receive three TQVOlllt'lOllS per interval from the rate wheel R3. Of course, it is to he understood. that these specific numbers apply only to the particular drawing of the system as shown in vFig. 2, and

shaft and the time shaft, would he changed correspondingly. It will he noted that the impulseshaft 2's makes four revolutions during an interval; the same number of revolutions as does the highest rate wheel. R4. This does not in any way interfere with the actuation of a register at a lower rate. for the reason that it is the wage disks which control the nun'ihcr of impulses that shall pass during an interval. For instance. in the example above assumed, where the register of workman No. l is connected in circuit at a live-cont rate, the wage disks 1rd]. W12 and writ-i revolved onl v once during an interval to allow one cycle to pass, thereupon breaking the circuit. So that. although the impulse shaft is made'threc further revolutions during that interval, no inirmlscs were sent through the registers during those revolutions. in order that the circuit through the individual job registers and the job totalizcr be completed, it; is necessary that the wage disks and job disks revolve in .s vnchroi'iism.

Inasmuch the circuits through any of the other wage registers can be readily traced in a manner similar to the circuit trwcd in detail in connection with wage rec -ter W1, I do not deem it; necessary to trace the circuits through each one of the wage registers. Thus, for instance, the circuit through wage register 2 would be through segment No. 2 of wage selector WS The circuit through wage register XV?) would be through segment No. 5 of the wage selector and seg ment No. of the time selector, and so on with the other registers.

that with a different series of rates the gear" ratios between the actuating shaft, the rate that is to say, it makesclosed through the contacts of any plug will The operation of the rate controller is such that when the brushes H) and in?) engage segment 1 of their respective selectors, the rate brush 7]) also engages segment 1, as shown in Fig. Similarly, when the register circuits are closed through segment No. 2 ot the wage selector and the time selector, the circuit through the rate controller is closed through segment No. 2. This simply means that the circuit through the registers ct worli'nnui No. 1 will be closed only when the collector brushes a), in?) and rZ engage each their associated segment No. 1. 1n the same way, the registers for workman No. 2 can be actuated only when the brushes engage segment No. 2, and so on with the other workmen.

Directing attention to the plugs jpl to j iG, it will be noticed that each plug has a pair ot normally closed contacts; that to say, these contacts are closed when the plugs are in the out position. hen, however, any plug'is inserted in the switchboard JS, those two contacts are separated. The purpose ot this arrangel'nent is to balance the actuations of any individual wage register in some other register, no matter whether the workmaus plug is inserted in ajaclt i the switchboard JS, or happens to be in the out position. When we traced the circuit tor the wage register Wl, we observer that from the switch Pl one branch of the circuit led through the wire 51 to the plug jpl, and from there to the conductor 52, to the job register J1. This was because, the plug jpl being inserted in one ot the jacks, the spring contacts of the plug were open and the only path for the current was through the conductor 52. However, it the plug jpl had been in the out position, as the other fire plugs are shown in Fig. :2, then the spring contacts would have been closed and the circuit would have been from conductor 51", through the spring contacts of the plug, to conductor (50, to the waste wage register VT, and from there through the conductors 56, 57 and 58 back to the main. m. So that, when the workman throws his individual switch into the in position, the actuations of his wage register will be balanced either in onset the job registers J1. to J6, or in the waste-time register \VT, depending upon whether his plug is in a job jack or in the idle position. It will be noticed that the conduct or (30 is a common conductor for one side of all of the plugs. In this way, any circuit that is be completed through the waste wage register \VT.

It will therefore be understood, from the above description, the workinens individual registers are picked up one at a time to be actuated every hour an amount corresponding to a Work-mans particular rate of wages, and that the individual wagc-regis ters can be actuated only through the wage total register T. In this way, the totalizer lVl will indicate the total of the wages, both productive and non-productive, accruing in connection with the jobs handled by the system. Each of the job regtatrrs ill to J0 will indicate the cost of any particular job so tar as that system is concerned; while the job total register Jl, through which the circuits ot the indiridual job registers are completed, will indicate the total cost ct the jobs taken care oft by the system. The wastewagc registers W! will indicate the amount of iunin'oductire wages; that is to say, wages which accrued to a worlnnau during a period in which he was not assigned to some particular job.

In the precise arrangement shown in Fig. 2, the wage total registers. as well as the worknicns individual wage registers and time registers, may be dccuijuulated,---that is, set back to zero, in the following manner: The switch .r is moved to the right in engagement with contact, 3 while. the switch a; is moved into engagementwith the asso ciatcd contact 3/. The workmens indiridual switches P1 to P6 are moved to the in position. For the decumulation ot the reg isters, the actuating shatt AS is rotated in the reverse direction from that indicated by the arrow on the disk 30. This will cause the rate shatt ES to rotate in the direction opposite to that indicated by the arrow. in order to deciunulatc automatically both the time and the wage registers together, the rate shaft is connected for actuatitai with the actuating shatt- AS the same as during accumulation. The. rate to e will. therefore all remain in tilt. rate switchboard RQS in their normal PO-wlllUll-S. It with the shaft RS rotating in the direc tion indicated by the arrow, the registers are actuated torwardly by the threephase ci'u'rent impulses, a 1'Q\'Ql'. tli ol order in which the impulses are impre upon the registers will result in the actuation at the register in the reverse or backward direction. This was :lully explained in connection with the detailed description of the three-phase motor shown in Figs. 5 and 'Z. The. decumulating circuit. may, there fore, be traced from the point to condnetor 40, through the wage disks to conductors ll, l2, 4-3, into the wage-total register WT, thence to conductors etla, i2. 23a. From these conductors the circuit will be completed successively through the indiridual wage registers to the discharge selector US. \Vhcn we traced the accumulating cults ot the wage registers (or. to he more specific, that of the wage register \a we found that from register lVl the current. passed through conductor it to the w e selector WS and from there to the in selector. However, inasmuch as the switch. discharge, in the position where it engages the contact y, the connection between the wage selector and the time and the discharge brush (it) is connected with the time brush. This means that the decumulating circuit of the a: is, during the selector is broken wage register must be completed through the thence to segment 1 through conductor to to point 1. There the circuit divides in the manner explained when the accumulating cir uit was traced, except, however, that the return path for the wage registers will be not through the job registers as before, but will be through the plugs jpl to jpG, conductor (3U, conductor 62, contact point y, switch arm a:', and through conductor 59 to the negative main m. The contacts 2 associated with each wage register are controlled by the highest-order numeral wheel of the register; that is to say, these contacts are normally closed highest-order numeral wheel has just passed beyond zero. At that ins-ant, a suitableproiectiou on the highest-order wheel strikes the insulated extension .2 carried by one of the contacts, and forces the contacts apart, thus breaking the circuit through the register. 'l'he contacts remain open until the register is again actuated forwardly. I

have shown these contacts in connection with the register illustrated in Figs. (3 and 7, but l have not. thought it essential to illustrate the interior mechanism of the register to show how the highest-order numeral wheel opens these contacts when the register passes through zero. ()ne way of carrying this detail out in practice is shown in my application referred to in the beginning of this spta-itication. ()lwiously, various ways may be devised for accomplishing the same purpose. For instance, in Fig. 11 which will be described in detail later on, I have shown a pair of normally closed contacts which are separated when the register passes through zero by one of the contacts dropping into a depression or recess in the highcst order numeral wheel. In this particular arrangement, the resiliency of the springs constituting the contacts is such that they normally tend to separate, but are not permitted to separate until the moment when the register pas es through zero. In the arriuigemcnt above described in connection with the wage registers, the Zero contacts 2 normally tend to remain closed and are forced when apart. by the highest-order wheel it passes through zero. Any other may be employed for automatically the ,jir out of circuit as soon as "ed or decuniulated.

-,..auiattizig circuits the other in.-

associated contacts .2 to conductor 61, segment 1 of the discharge selector DS, of the time selector, plug Pl, thence to and remain closed until the to be borne in mind in this connection is that contacts of register W3 connect with ment 3 of the discharge selector, etc. As

soon as any one register has been brought: back to zero. it: will be autoniatically cut out of circuit without any attention wlnitsoever on the part of the individual in charge of the decumulating. The decumulation ot' the registerswill usually take place during the night, or at a time when the system is not accumulating.

To this description of the shown in Fig. 2, I have to add that other such simple systems may be connected to be controlled by the same and similar mechanism that controls the first system. For instance, the time registers of the second and third systems would be connected to the conductors 48, 41-9 and 50. The workmens individual switches would be connected onto the conductors which lead to the segments of the time selector TS, while the individual wage-registers would be connected with the six conductors which lead to the six seg ments of the wage-selector Wb. The job switchboard would, of course,

simple system be duplicated and the individual job registers connected in a manner similar to the connections of the individual job registers J] to J0. For instance, job register J1 ol. the second system would be connected with the first strip of jacks of a job switchboard, just as the job register J1 of the system shown is connected with the first strip of jacks of the switch- I board JS. The job registers J1 to J6 of system No. 2 are connected with the job totalizer JT', just as the individual job registers J1 to J6 of system No. l are connected to have their accumulations totalizced in the job total register JT. In like manner are, the individual job registers J1 to JG i of the third system to be cminected with their totalizer JT. Systems 2 and 3 have waste-wage registers lV'T, WT respectively, arranged each to be connected with the plugs of the associated switchboard. just as the waste-wage register XVI of system No. 1' connected with the plugs i721 to 7776. The c irrent passing through the conductors 41, 42 and 43 from the wage disks, will find parallel paths through the wage totalizers of the three systems, ust as the correspondg registers of the individual systems are nnected up in parallel. The wage total more :tor systemsllo. 2 and 3 are indiduring the discharging, the circuits of the catecl respectively at YVT and WT. In other words, while the individual registers of each system operate corresponding regis'le ott' the systems operate concurrently in parallel circuits. W'th this arrangement, there is the limitation that the corresponding wage registers can operate only at the same rate. So that, if workman No. 1 of system No. 1 works at five-cent rate, workman N o. l of system N o. 2 will also be connected up at that rate, and the same with workman No. 1 or No. 3. However, this arrangement mayin many cases not be found undesirable or objectionable, In case it is imperative that the corresponding wage registers of the several systems should be capable of operating at difl'erent rates, it is only necessary to provide each system with a circuit controlling mechanism similar to that shown in system No. l. lVith the systems connected in parallel with a common controlling mechanism, it is not necessary that the corresponding individual job registers shall operate at the same rate. For instance, if job register J1 of system No. l is actuated through the job totalizer JT at the rate of say five cents an hour, the corresponding job register J1 of system No. 2 may he actuated through the associated job totalizer JT at the rate of twenty cents' an hour.

I might, perhaps, at this point call attention to the three isolated circles appearing in connection with each of correspondiim registers of the several systems, as indicated in the upper right hand portion of Fig. 2. It will be remembered that in the introductory partof this specification I referred to reservoir substations into which the simple systems discharged, these substations consisting of composite motor units for accumulating the actuations of the simple sys tems and transferring them into the generic or grand-total registers at the central station. These composite motor units consist each of a transfer member and as many accumulating members as there are systems discharging into the substation. In the particular embodiment of my invention as illustrated in Fig. 2, there are three simple tems discharging into a substation. In such a substation, each motor unit will, therefore,

' consist of three accumulating members. in

there are indicated nine composite Fig. 2, motor units. The three accumulating members of each motor unit are represented by the-registers J1,-l1,J1to J6, J6, J6; ll T, VT, WT; VV'T, lVT, lVT; and JT, JT, JT". The transfermembers with these sets of accumulating members are diagrammatically indicated by the three isolated circles appearing above each set of accumulating members, and lettered TM]. to TMG, TllflV, TMVV and TMJ, respectively. Considering, for the sake of illusintercurrently, theassociatedtheir actuations are totalized by I I. l I l tration, the first or the composite motor units indicate-cl in Fig tie regisiers J1, J1 and J1 are so connected it e' "hcr that ter of the transfer member Tan. This reg ister is provided with a pair of zero-contacts for automatically opening circuitthrough the eleclron'iagnets associated therewith whenever the reg'stcr is brought to zero. The transfer rcgiter is adapted to be actuated by its mcr.:hanism in a direction reverse to that in which it is actuated by the accumulatingmembers J1. .ll, J1.

whenever, therei'mre, the transfer register is a tuated above ZCI'O by the 'ociated :wcuinulating members, the circuit. through the actuating IHGCllfllllHll of the trans'i'm: r 'sier is automatically closed, and the i'egis 7 er set back to Zero by l ingdischarged into the proper generic register at the central station. Before, however, taking up the circuit arrangements whereby the trans discharging effected, it will be h t to refer in detail to the structure of the composite motor unit as shown in Figs. 9 and 10, in order to first arrive at an understand ing of the precise operation of this mecha- -1ism.

The accun'iulatine members 3111, .2, .li ill, consist each of the "three-pha..e

motor device shown in Jigs. l and 7 and already lescribed in detail. The armature shafts 081, N82 and na l, respectively, cl these accumulating .i'i'ieribei's are each provided with a worni gear T0. in this way the shaft of member Ahll s connected with the spiral ,Qear Tl. This gear is cinnecled with the sleeve 72?, which is rotatahly carried by the vertical shaft 73. The upper end of this sleeve is PI'OVltlQd with the bevel gear T l, which constitutes one of the side members of a ditlerential set, of which the central member is the spiral gear 75 and the other side member the bevel gear 76. The spiral gear T5 is connected with the armature shaft is-i through the worn: gear 70. The. le men'ibers 74 and There connected together by the bevel pinion 77. pivotalbf carrier. by the spiral gair 75. The bevel gear 76 is mounted upon one end of the sleeve 78, ro-

I l The upper end of tatable on the shalt 43. this sleeve is provided with a bevel gear 79, which constitutes one of the side members oil" a ditlerential set similar to the one just described. The central member 80 of this differential set is con noel ed with the armature shat't as? through a woringear. The bevel 79 and 81 are connected together by the bevel pinion Si, pivoted in the spiral gear 80. The bevel gear 8']. is carried by one end of the sleeve 33. the other end of which terminates in the bevel ,e'eaii' 84. As already explained, the accumulating" members are positively actuated by the three-phase current impulses sentthrough thewindings.

Tu order that these actuations may be properly totalized, the respective armature shafts of these members are actuated in reverse directions, as indicated by the arrows in Fig.

10. it will be a1' parei1t that by means of this differential connection between the armature shafts of the accumulating members AMi. AMQ, AMI-3, the aetuations of these members are accumulated, so that the rate of actuation of the bevel gear 8t will be equal to the sum of the rates of actuation of the individual accumulating member. So far as accumulatingthe actuations of the members AMl, AMQ, AM3, it is not necessary that the armature shafts of these mei bers be connected to individual registers. It may in certain instances be desirable to in so in order to have separate indications of the amount of actuation of each accunnzlating member. In this case the armature shaft of each accumulating member may be connected with a register, as shown inFigs. 6 and 7, and as diagrammatically indicated in Fig. 2 by J11 J1, J1", etc, etc. The transfer member TM also consists of the threephase actuating device shown in'Figs. 6 and 7, the same as the accumulating mem bers. The armature shaft asst of the transfor member is connected with the spiral gear 85 through the worm 86. This spiral gear is mounted upon the upper end of the sleeve 86, the lower end of which is provided with the bevel gear 87. The bevel gears 87 and 8tconstitute the side members of a differential set, of which the central member is the large bevel gear 88. The bevel pinion S9, pivotally carried by the central gear 88, connects the side gears 87 and St. The large bevel gear 88 meshes with the small bevel 'gear 89. which is rigidly connected with the gear 90 and supported on a shaft not shown. The

gear 90 meshes with the pinion 91 carried by the actuating shaft of the transfer register TR. With this construction it will be seen that the motion of the bevel gear 8t. if we imagine sleeve 86 to be stationary, is transmitted to the central gear SS by the pinion 89 climbing around the bevel gear 87. From gear 88 the motion is transmitted to the register through the interposed gear just described. Any one or more of the motors in the composite motor unit may be run as a transfer motor irrespective of the actuation of the others, and the same is true in regard. to accumulation actuations. Now, the transfer register TR is provided with zero contacts 20 similar to the individual wage-registers as previously described.

in the diagrammatic representation of Fig. 2 the register has been entirely omitted from the composite motor units, in order not to complicate the drawing unnecessarily. These zero contacts are adapted to open the circuit through the electromagnets of the .Clllllllliii'lODS occur.

member every time the register reaches zero. However, as soon as the register passes above zero, the contacts are closed and the shaft as actuates the sleeve '86 in the direction indicated by the arrow in Fig. 10. This actuation of the sleeve is transmitted to the large bevel gear 88 and from there to the register, to actuate the same in a reverse direction. In other words, supposing that the transfer register TR is at zero, the circuit through the elcctromagnets of the transfer member TM will, therefore, be opened and the sleeve 86 will be stationary. The actuations of the accumulating members will be transmitted into the transfer register through the path previously described. As soon, however, as the register is actuatedabovezero, the contacts 20 are closed. This completes the circuit through the electromagnets of the transfer member, and the sleeve 86 is actuated to bring the register back to zero by actuating it in the reverse direction. As soon as Zero is reached the circuit through the transfer member is again interrupted and the register again,

accumulates. This cycle of operation is repeated over and over again, and the entries made in the transfer register maybe withdrawn or transferred as fast as they are made, or subsequently.

lVe shall presently learn that the same number of impulses which pass through the transfer member to bring the register back to zero also pass through a totalizing register at the central station. In this way it will be seen that the actuations of the individual accumulating members in a substation are transferred and totalized into the central si'ziiiOll. However, it is not necessary that this transfer take place as fast as the aclVe shall see later on that the circuits of the transfer member may be held open even though the transfer register is above zero. This permits the individual accumulating members to be totalized in the transfer register and held therein for transfer at some future time. The transfer motors comprising a substation operate concurrently; but the corresponding motors of the different substations operate successively, as shown in the drawings. This will be made armarentwhen we take up the description of the transfer or discharging-circuits and controlling devices shown in Fig.

"It will now perhaps be appreciated why I have come to designate the substations as reservoirsubstations. The inflow produced by the accumulating members is entirely independent of the outflow, which is con trolled by the transfer member. The inflow may either be stored in the reservoir for future withdrawal. or the withdraival may take place as the'inliow accumulates. Just how the composite motor units transfer the aet'uations of the accumulating members into he proper register at the central station is l ed on the selector shaft SS.

and 12 to involve any one of the total cost registers with any pi'ei,lctt- .rinincd entry I shall take up the description of the structure as shown in these figures before attempting to trace the circuits in Fig. 3 for adding the cost of material or any other similar entry into any one of the total cost re isters.

In the end members 150 of the housing inclosing the register mechanism is mounted the stationary supporting shaft 151. Upon this shaft is rotatably mounted a series of sleeves 152, 153, 154 and 155, Upon the sleeve 152 are secured the units wheel 11. the carrying wheel 156, the hand wheel 157 and the gear Wheel 158. Similarly, upon the sleeve 153 are rigidly iounted to rotate together the tens wheel 2., the carrying wheel 1565, the hand wheel 1572f and the gear wheel 158$. Upon the sleeve 15% are secured the hundreds wheel. 71, the carrying wheel 156/1, the hand wheel 1577i and the gear wheel 1587a. Upon the sleeve 155 are rigidly mounted the thousands wheel 6w, the hand wheel 157", and the gear wheel 158'. The highest order numeral wheel has, of course, no carrying mechanism associated therewith. The hand Wheels extend through openings 159 in the casing 160, in which the mechanism is housed. On top of the casing are the sight openings 161 for the numeral wheels. The sleeves on which the four numeral wheel sets above described are mounted are separated by the spacing members 162. he actuating shaft 163, mounted in the ends of the casing, is adapted to be actuated by a three-phase motor device such to the transfer member TMl, thence through the associated zero contacts to the common conductor 112'. From there on the circuit is as traced above in connection w ith the transfer member of substation S1. hen the shaft SS is actuated to bring the selector brushes (Z into engagement with segments No. 3, transfer member Th/ of substation S3 is selected for discharging into the total izing register TCl. From this it will be seeiithat the corresponding transfer members at the different substations are selected successively one at a time for discharging into the proper register at the central station. However, the transfer members of any one substation, being all connected in' parallel, will discharge concurrently into their respective totalizing registers. Thus, transfer member TM2 of substation S1 will discharge into totalizing register TC2 concurrently with the discharge of transfer member TMl into totalizing register TCl, provided, of course, that adischarge plug is inserted in the jack 72. Transfer member TM3 of substation S1 will discharge into the totalizing register T63 across the contacts of jacks j3, etc., with the other transfer members.

will now explain how the totalizing registers may be cleared. To'do this it is only necessary to insert the clearing plug GP into the jack of the register to be cleared, and to open the switch S. Let us suppose that register TCl is to be cleared and that the clearing plug CP is inserted in the jack jl. The circuit may then be traced as follows: from the positive inain M to conductor 125, clearing plug GP, spring contact 116 as s shown in Figs. 6 and 7 previously deof jack 7'1, conductor 126, then across the scribed. Upon this actuating shaft is zero contacts 20, through the register TCl. mounted a series of differential sets comprisconductors 118, 119 and 120, impulse disks- ID, thence through conductor 121 back to the negative main M. As may be seen from the detail view of Fig. 4, when the clearing plug is inserted in a jack the spring contacts 11% and 116 engage the insulated head of "is clearing plug so that no circuits can be closed through these contacts. As soon as the register has reached zero, the associated mg each a central gear 164 and two side gears 165. The pinion 166, mounted in the central gear 161-, engages the side gears 165. The first of the bevel gears 165, viz., that shown adjacent to the right hand partition 150, is firmly fixed upon the shaft 163 as by means of the pin 16?. The adjacent side members of the first and second differential sets are secured to the sleeves or hubs 168 and 169, respectively, on the shaft 163. Likewise, the loose hubs 170 and 171 support the adjacent side members 165 of the second and third differential sets. The hubs 172 and 173 carry the adjacent bevel gears 165 ofthe third and fourth differential sets. The sleeve member 171- carries the last of the side gea rs of the fourth differential set. Upon each of the hubs 168. 170, 172 and 174 is also mounted an actuating gear 175. These actuating gears engage the gears 158, 1582i, 1587i and 158,.which are associated with the different numeral wheels as just described. The hubs 169, 171 and 173 explained, register beyond zero is prevented. In the same manner may the other total cost registers be cleared by simply inserting the clearing plug in the proper jacks.

I have yet to explain the mechanism by which any desired amountmay be entered totalizing registers in addition to the amounts transferred into these registers from the substations. It is obvious that the total cost of a job will consist of more than merely the amount of wages paid out. There is, for instance, the
